It's been shown to have no benefit when someone is near-dead from COVID. Don't 80% of people on ventilators die anyway? So ventilators have no benefit. From what I have been reading, the drug does have benefit when used as a prophylactic, in combination with zinc. Of course we now have politicized medicine due to the fact Trump is taking it, and whatever Trump does must be de-facto bad. Now we have countries banning it's use, because of the WHO, who also said masks are useless.
Given that the entire world is studying these drugs, and many nations have now suspended their research, I don't think you can chalk it up to a single person, unless you're assuming the entire world is defining their own medical and research policies based upon Twitter outrage.
The WHO is not advising stopping all HCQ trials but has only dropped HCQ from the Solidarity Trial, and that many prophylaxis trials using HCQ are ongoing or about to start.
